Altcoins Outshine Bitcoin in Longest Winning Streak of 2025
The cryptocurrency market has entered one of its strongest altcoin runs in recent memory, with trading volumes surging and investor sentiment shifting rapidly.
A fresh analysis from 10x Research shows that altcoins have now maintained an edge over Bitcoin for 31 consecutive days, marking the longest stretch of altcoin dominance in over a year. This comes amid a sharp rebound in global trading flows and Ethereum’s rally toward price levels last seen in 2021.
Altcoins Hold the Lead for 31 Days
10x Research’s tactical altcoin model, which gauges capital rotation between Bitcoin and alternative cryptocurrencies, has favored altcoins since early July. The streak surpasses the November 2024 high of 25 days and the March 2025 peak of 19 days. According to the report, Bitcoin’s market share has steadily slipped while the total crypto market capitalization has climbed, fueling optimism for a more prolonged altcoin cycle.
Ethereum and Global Trading Surges
Ethereum’s breakout is a major driver behind this momentum. The token has rallied toward price levels not seen since late 2021, attracting renewed interest from both retail traders and institutional desks. Meanwhile, South Korea has emerged as a key player in the latest rally, with a weekend trading volume spike exceeding $4 billion — a sudden influx that signals strong speculative demand in Asia.
Macro Events Add Fuel to the Rally
Geopolitical developments have also played a role. Concerns of a potential clash between U.S. President Donald Trump and Russian President Vladimir Putin initially weighed on markets. However, reports suggest Trump has reached a strategic understanding with the EU by increasing arms sales to Ukraine while signaling a willingness to discuss land concessions in Eastern Europe. This has eased investor concerns and reduced the likelihood of a sudden market pullback.
Why This Rally Could Be Different
While similar altcoin rallies in the past year have fizzled quickly, 10x Research suggests the current breakout may prove more sustainable. Broad-based gains across multiple altcoins, combined with strong regional trading spikes and favorable macro shifts, have set a foundation for continued capital rotation away from Bitcoin.
What to Watch Next
Traders will be closely monitoring Ethereum’s ability to maintain its breakout, Bitcoin’s resilience above key support levels, and whether South Korea’s trading boom spreads to other Asian markets. If these trends persist, the ongoing altcoin run could stretch deep into the fourth quarter, challenging Bitcoin’s dominance in ways not seen since the previous bull market.

It started in 2016 with Bitcoin. Like most people at the time, he didn't fully understand it - so he kept digging. Blockchain, tokenomics, the projects, the cycles. That curiosity never stopped, and eventually pulled him into traditional markets too: equities, commodities, macro. Not because he left crypto behind, but because you can't properly understand one without the other. What drives him is straightforward: he wants to know why something is happening, not just that it's happening. Most market coverage stops at the headline - price up, price down, here's a chart. Alex finds that kind of reporting actively unhelpful. If you walk away from an article without understanding the mechanism behind the move, what did you actually learn? He holds a degree in Tourism from New Bulgarian University - not the most obvious path into financial markets, but markets have a way of pulling in people who are simply too curious to stay out. He has authored over 200 in-depth analyses and more than 10,000 articles across crypto and traditional finance. He still thinks every day in markets teaches him something new. That's probably why he hasn't stopped.
